Pediatric diarrhea is a condition caused by various causes and factors, mainly characterized by an increase in the frequency of bowel movements and changes in stool characteristics. A portion of this condition is caused by bacterial infections, particularly in the summer when enterotoxigenic Escherichia coli gastroenteritis is a likely cause. In such cases, children may experience vomiting, persistent diarrhea, and severe dehydration. Additionally, if the child's stool contains mucus and pus, or is a pus-blood stool, it is generally considered to be caused by bacterial dysentery bacilli. If the stool is jam-like with more blood and less stool, amoebic dysentery should be considered. Other invasive bacterial infections, such as invasive E. coli gastroenteritis, jejunal Campylobacter gastroenteritis, or Salmonella gastroenteritis, are also common bacterial infections.
